Diamante was no weakling. He could even be counted among the strongest in the first half of the Grand Line, and he knew two types of Haki.
But the Rumble-Rumble Fruit's abilities were simply too outrageous. Karn had merely manipulated the bioelectric currents inside Diamante's body, delivering a powerful shock to his internal organs, brain, and blood vessels throughout his body, knocking him unconscious on the spot.
This was only the most basic method, and Karn had trained for a long time to reach this level. Once he became proficient enough to control bioelectricity more precisely, he would be able to alter Diamante's five senses, consciousness, and memories, turning him into a puppet.
Diamante's sudden collapse shocked and enraged Gladius beside him. They represented Doflamingo, yet one of them had been detained and another knocked unconscious.
"You-you've got some nerve! We're the Donquixote Family!"
"Keep talking, and you won't be leaving either."
Crackle.
Karn calmly interrupted Gladius's threat. At the same time, four solid spikes of lightning appeared around Gladius's body, making his heart leap.
After a moment's thought, Gladius hoisted Diamante, who lay foaming at the mouth, onto his shoulder and ran outside. As he ran, he shouted, "I'll report this to the young master! The Donquixote Family won't let you get away with this!"
"He still dared to threaten you before leaving, boss. Do you need me to get rid of him?"
Nico Robin stepped forward and asked. Lowering her eyes toward Karn, she noticed that he had already reached out to hold Baby 5's hand. The cigarette-smoking woman was so bashful that she did not even care that her companion had been beaten.
A strange woman meets a lecherous boss! Nico Robin thought. Perhaps her boss had been searching for this woman not for her Devil Fruit
